The proposal was driven by concerns over electricity demand, water use, wastewater, noise, local tax deals and whether rural permitting systems are built for hyperscale projects.

The winners are straightforward: data-center developers, utilities and municipalities that want projects moving before a tighter statewide framework arrives. The losers are the lawmakers and local officials who wanted time. The bill, backed by **Rep. Melanie Sachs**, would have paused new projects above **20 megawatts** until **Nov. 1, 2027**, created a **Data Centre Co-ordination Council**, and required a report by **February 2027** before large-scale buildouts resumed.

CNN reported earlier this month that Maine’s bill had bipartisan support and sat within a wider wave of proposed moratoriums and local restrictions in states including **New York, South Carolina, Oklahoma and Vermont**.

That risk is growing fast. The **U.S. Department of Energy** estimates data-center electricity use has **tripled over the past decade** and could **double or triple again by 2028**, reaching about **12% of U.S. electricity demand**.

In the wider [US Politics](https://modeldiplomat.com/discover/us-politics "modeldiplomat.com") and [United States](https://modeldiplomat.com/country/usa "modeldiplomat.com") debate, states face a hard trade-off: block projects and lose tax base and construction spending, or approve them quickly and risk locking ratepayers into grid upgrades before demand forecasts are proven. AP has reported that regulators and lawmakers are already questioning utility load forecasts tied to data centers because some projects remain speculative or may be double-counted across service territories.

Just as important: whether developers move quickly to file projects while statewide rules remain unsettled. **Mills won the timing fight.** The real test now is whether Maine can write a framework before project momentum outruns state control.
